[0025] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.
[0026] An atmosphere lamp is provided according to an embodiment of the present application, which has promoting effects in terms of energy consumption, light brightness, cost and space occupation. Figure 1 A structure schematic diagram of an atmosphere lamp according to an embodiment of the present application is shown.
[0027] Figure 2 An exploded structure schematic diagram of an atmosphere lamp according to an embodiment of the present application is shown. As shown in Figure 1 and Figure 2 An atmosphere lamp includes a light emitting source 100 and a light guide 200. The light emitting source 100 includes two lamp beads (not shown in the figure), which emit light rays towards the entrance of the light guide 200. The light rays propagate along the pipeline in the light guide 200, forming a lamp strip effect.
[0028] Figure 3 A structure schematic diagram of the light guide 200 in an atmosphere lamp according to an embodiment of the present application is shown. As shown in Figure 3 The light guide 200 has a first input section 210, a second input section 220 and an output section 230. The first input section 210 and the second input section 220 are close to the light emitting source 100 and are respectively arranged corresponding to the two lamp beads. The first input section 210 and the second input section 220 are combined and extended into the output section 230 on the side away from the light emitting source 100.
[0029] In the prior art, the light guide 200 has a single tubular structure. The light rays emitted by one lamp bead are irradiated towards the entrance of the light guide 200, so that the light guide 200 is illuminated, forming a lamp strip effect. The length of the light guide 200 is relatively long. In order to make the light brightness of the entire light guide 200 uniform, the light emitted by the lamp bead needs to have a relatively high brightness.
[0030] In the embodiment of the present application, the light emitting source 100 includes two lamp beads, which emit light from the entrances of the first input section 210 and the second input section 220, and then pass through the output section 230. The output section 230 can be understood as a light guide section exposed and displayed. The first input section 210 and the second input section 220 can not be exposed or can be partially exposed.
[0031] The atmosphere lamp in the embodiment of the present application emits light through two lamp beads to obtain a lamp strip effect. Two small-power lamp beads are relatively one double-power large lamp bead, and the cost is cheaper. The power of the two lamp beads is slightly higher, and the brightness is much greater than that of one lamp bead. That is, it is easier to improve the total brightness of the two lamp beads than to improve the brightness of one lamp bead, and the cost is lower. In this way, the atmosphere lamp can obtain higher brightness and improve the atmosphere effect.
[0032] In an embodiment, the light guide member 200 further includes a connecting rod 240, which is fixedly connected with the first input section 210 and the second input section 220, so as to attach the first input section 210 to the second input section 220.
[0033] As shown in Figure 3 In order to close the two input sections and reduce the occupied space, the first input section 210 and the second input section 220 are fixedly connected through the connecting rod 240, so as to ensure the shape of the input section and facilitate the installation of the light guide member 200.
[0034] In an example, the two input sections can also be fixedly connected through glue joint during injection molding. The range of the glue joint can extend from the head to the tail of the first input section 210 and / or the second input section 220, or can be a local range of the glue joint.
[0035] In an example, the first input section 210 and the second input section 220 are communicated through the side wall channel 201, and the width of the side wall channel 201 is less than 1 / 3 of the diameter of the first input section 210 and / or the second input section 220, so as to avoid the early mixing of the two light beams and the loss of light power caused by refraction.
[0036] In an embodiment, the connecting rod 240 is arranged close to the light emitting source 100, so that the input section close to the light emitting source 100 can maintain a fixed shape, and the entrances of the two input sections can be easily directed to the corresponding lamp beads. On the other hand, the installation and fixation of the two input sections can also be facilitated.
[0037] In an embodiment, the first input section 210, the second input section 220, the output section 230 and the connecting rod 240 are integrally formed to obtain the light guide member 200. This facilitates production and can also make the structure and performance of the light guide member 200 stable, without extra gaps, to avoid light leakage and the like.
[0038] In an embodiment, the light source 100 further comprises a lamp holder 110 and a PCB board 120. The two lamp beads are electrically connected to the PCB board 120, and the PCB board 120 is connected to a power supply through a wire harness 500, so that the lamp beads can emit light after being powered on.
[0039] Figure 4 A structural schematic diagram of the lamp holder 110 in the atmosphere lamp according to an embodiment of the present application is shown. Figure 5 Another structural schematic diagram of the lamp holder 110 in the atmosphere lamp according to an embodiment of the present application is shown. Figure 4 and Figure 5 As shown, the lamp holder 110 is an injection molded part, and the lamp holder 110 is provided with a first recess 111, and the PCB board 120 is clamped in the first recess 111. One side of the first recess 111 is provided with a light outlet hole 112, so that the two lamp beads face the light outlet hole 112.
[0040] The two lamp beads are fixed on the PCB board 120, and then the PCB board 120 is installed in the first recess 111, and a cover plate 130 is further arranged on the PCB board 120 to fix the PCB board 120. The two lamp beads are directed to the first recess 111 and face the light outlet hole 112, so that the light emitted by the two lamp beads can be emitted through the light outlet hole 112. In an embodiment, the side of the lamp holder 110 away from the first recess 111 is provided with a protrusion 113, and the light outlet hole 112 penetrates the protrusion 113. The protrusion 113 is provided, that is, the light outlet hole 112 is extended, so that the two input sections of the light guide member 200 can be inserted into the light outlet hole 112 to receive the light emitted by the two lamp beads.
[0041] In the embodiment of the present application, the two input sections are provided, so that the input section of the light guide member 200 is flat, so that the light guide member 200 is more easily fixed in the light outlet hole 112. Compared with one input section, one input section is circular and easy to roll, which will loosen and fall over time, so that the service life of the atmosphere lamp is shorter.
[0042] In an embodiment, the shape of the light outlet hole 112 is adapted to the end portion formed adjacent to the first input section 210 and the second input section 220, so that the heads of the two input sections can be inserted into the light outlet hole 112 to be fixed, improving the installation effect and efficiency of the light guide member 200.
[0043] In one example, the PCB board 120 and the cover plate 130 can also be arranged on the side of the lamp holder 110 away from the first recess 111, which can be set according to actual conditions in specific applications.
[0044] In one example, the head of the two input sections in the light guide 200 can be injection molded into a shape that fits the light exit hole 112 to more stably insert the light guide 200 into the light exit hole 112. It can also ensure that the two lamp beads correspond to the first input section 210 and the second input section 220, respectively.
[0045] In one embodiment, as shown in Figure 6 The light shielding cover 300 includes a lamp head portion 310. The lamp head portion 310 is provided with a second groove 301 that is shaped to fit the end of the lamp head 110 near the protrusion 113. The sidewall of the second groove 301 is provided with an opening to allow the end of the lamp head 110 away from the protrusion 113 to pass through.
[0046] As shown in Figure 2 The lamp head 110 only needs to be clamped in the lamp head portion 310 near the protrusion 113, and the rest can pass through the opening.
[0047] In one embodiment, the light shielding cover 300 further includes a guide bend portion 320. The guide bend portion 320 includes a third groove 302 that communicates with the second groove 301. The third groove 302 is used to mount the first input section 210 and the second input section 220, so that the first input section 210 and the second input section 220 are clamped behind the light exit hole 112 and extend along the guide bend portion 320. The length of the guide bend portion 320 is 1 / 10 to 1 / 2 of the length of the first input section 210 or the second input section 220.
[0048] The provision of the guide bend portion 320 can facilitate the installation of the light guide 200 and avoid the bending of the light guide 200, which affects the light exit effect. The length of the light guide portion can be set according to the use scenario of the ambient light. In the case of complex installation environment of the ambient light, a longer guide bend portion 320 can be set to ensure that the two input sections of the light guide 200 are not bent. In addition, the size of the space can also be considered to set the guide bend portion 320 with a shape and size that adapts to the installation space.
[0049] The ambient light of the embodiments of the present application can also include a mounting bracket 400 provided with a fourth groove 401 for mounting the light guide 200 to define the installation path of the light guide 200 and prevent the light guide 200 from being bent.
